Select the correct answer.
a baseball is thrown into the air from the top of a 224-foot tall building. the baseball's approximate height over time can be represented by the quadratic equation h(t) = -16t2 + 80t + 224, where t represents the time in seconds that the baseball has been in the air and h(t) represents the baseball's height in feet. when factored, this equation is h(t) = -16(t - 7)(t + 2).
what is a reasonable time for it to take the baseball to land on the ground?
a.
7 seconds
b.
2 seconds
c.
9 seconds
d.
5 seconds

The reasonable time for the base ball to land on the ground is 5 seconds

Step-by-step explanation:

To get the time we will differentiate

h(t) = -16t2 + 80t + 224, w.r.t t

dh(t)/dt= 0

-32t +80=0

32t=80

t=80/32

t= 2.5 seconds This is the time the base ball has been in the air

The reasonable time for it to take the baseball to land on the ground is T= 2×t

T= 2×2.5

T=5 seconds

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
